PLX don't have any "IO Accelerators" for PCI express.

They do make a PCI express to PCI converter though ;)

I dunno how much PCI-e soft cores cost, but it looks like one of the "easier" 
routes to doing PCI-e :( You need an interface chip (BGA..) unless you're 
using a Virtex-4 though (dunno what that translates to in Altera-land)
